Sept 04
Manual selection of the master AFCS channel is accomplished via the pop-up menu
on either multifunctional display (MFD), in conjunction with the MFD control panel
located on the pedestal.
AUTOPILOT
The autopilot (AP) system automatically controls the airplane in pitch and roll attitude
via servo control of ailerons, elevator and aircraft pitch trim system. The two autopilot
computer channels operate in a high priority/low priority (active/standby)
configuration.
Assignment of priority channel is alternated on power-up. The high priority channel
provides control functions, while the low priority channel operates in a back-up mode.
The autopilot/yaw damper actuators and pitch trim interface can only be driven by the
priority channel.
In the event of a channel failure, the priority will automatically switch to the other
channel.
Each FGC shall determine which symbol generator is driving the selected PFD, as
selected on the reversion control panel located on the pedestal. The following
guidance data is received via the Avionics Standard Communications Bus (ASCB), for
use in the FGC:
